Referring to Figs. l and 1) the machine in general comprises a horizontal base l on. which is mounted for rotation about a vertical axis, a blank mold table 2 and a bottle m'old table 3. Upon the blank mold table 2 are mounted four blank molds 4, in which a blank for a bottle or other glass article is formed from a gathering of glass supplied to the blank mold either by hand or by some automatic mechanism. Upon the bottle mold table 3 are mounted five sectional bottle forming molds -Which receive the blanks from the blank molds and in which the finished bottle or other glass article is formed.

In the process of manufacturing a finished bottle, a completed product by this machine, the glass is iirs't gathered in some suitable manner from the meltingl tank, adjacent 'which the machine is located, and this glass gathering is then sheared from the' gathering mechanism by a suitable shear above the blank mold. After the glass has been sheared and4 placed in the blank mold, the blank mold table is caused to rotate and carries the blank mold beneath a blank forming plunger. The plunger is caused to `descend into the blank mold thus forming a blank from which a bottle will subsequently be formed. After the blank is formed the table again moves the blank mold into another operative position where a transfer mechanism grips the blank after it has been raised partly from the mold by an ejector, and transfers it to a bottle forming mold mounted upon the rotary bottle mold table adjacent the blank mold table. After the blank has been deposited in the bottle forming mold the bottle mold table is caused to rotate until the bottle mold is eventually registered With a blow head or mechanism for blowing the blank into the formcf a bottle. If the blank is defective or what is called an over press, a selector will be actuated which will prevent the operation of the blowing mechanism. After the table stops, With the bottle mold in operative position to be blown, a mold lock is actuated and finally the blow head descends and the' blank is blown to form a bottle. After t e bottle is formed the blow head is raised a d the mold lock released. The bottle mold table is then lrotated until the bottle mold containingthe finished bottle is in operative. position to be 'extracted from the mold and placed upon a conveyer. Before the ml l is opened a bottle centering or positioning mechanism is actuated to retain the bottfa 'in proper position to bepicked up by the bottle take out or transfer. After the mold is opened the bottle is gripped by the A the machine will follow in the order of their operation as above outlined, beginning with the mechanism for shearing the gathered glass into the blank mold. Referring to Figs. l and 2, the shear comprises a bracket 6 adj ustably mounted upon the stationary central standard 7 about which the table rotates. Pivoted by means of the bolt 6 to the bracket 6, are the shear blades 8 and 9, and secured to each blade are the bevel gear segments 1Q and 1l respectively. Also jonrnaled at 12 for rotation is the bevel gear wheel 13 which meshes with the gear segments l0 and 11 and which when oscillated causes the shear blades'to move in opposite directions orto open and close. The engaging edges of the shear blades are provided withthe usual cutting edges.

The bevel gear wheel 13 is oscillated about its axis by means of the crank arm 1+ secured at one end to the gear shaft 15 and at the other end to a forked solenoid core 16 which is actuated longitudinally by the soienoid 17 secured to the standard 7. lllhen f the solenoid 17 is energized the core 1G is raised causing the bevel gear to be rotated in the proper direction to cause the shears to close and cut 0H a gathering ofglass, and when the electric circuite through the solenoid 17 is broken the shears are opened by the action 'of the spring 1S, Fig. 2

which is secured to the bracket 6 and pulls down the crank lever 14. The bracket (3 also supports the electric switch 19, and this switch is adapted to vbe actuated by the gathering mechanism (not shown) at such time as it is desired that the gathering should be sheared into the blank mold. The gathering mechanism may be operated either lmanually or automatically. To shear Ithe gathering of glass the pvunty, in the case ofa handfgathering implement, is brought in contact with the fiexible switch handle 20, Figs. 1 and 14, causing the solenoid to be energized and to close the shears. As soon as the` current is interrupted by the punty being disengaged from the switch arms Q0, the shears are 'opened by the spring l and remain open until the solenoid is again energized. i

'l and l pivoted to the shaft 57 pushing it down and thereby pulling down the valve lever 53 by means of the connecting rod 58 attached. to the free end of the respective levers.

The cam 55, Figs. and (l, is made in tivo parts having slots 59 cut `therein through which a clamping bolt 59 is inserted, the bolt serving to hold the tivo parts of the earn in adjusted positions. @ne of the cam me1nbers carries a sleeve G0 which is keyed to the shaft 27 by means of the key 6l. It will be seen that the cam surface of greatest radius may thus be shortened and lengthened, as the case demands, by increasing the length of the cam surface of greatest radius, the period of time which the valve lever 53 remains in lowermost position is increased accordingly, and the plunger is caused thereby to remain in the blank mold an eX- tended length of time. Y

rlhe purpose'ot' such adjustment .of the interval of time that the plunger is permitted to remain in the mold, is to compensate for wares of different size and Weight, the length of time the plunger should engage the -glass blank dependingI upon its size and shape. T he ladjustable cam provides a positive means ior regulating and controlling the action of the plunger and a means that when once adjusted to a certain size blank, will not vary as will regulating means not having a positive action. As has been previously disclosed, the shaft 27 makes one complete revolution to every movement ot' the moldsl and it is therefore possible to adjust the cam 55 in such position on the shaft that the valve will be operated at the proper intervals to insure the required results. The valve lever after being pulled down is returned to the position shown in .F ig. -l by means ot' the counter weight (32 adjustably mounted on thel eX- tended end of the lever After a blank has been pressed in the manner above descr-lined, and the plunger has been raised out ot the blank mold, the table is again'rotated a quarter revolution when the blank mold containing the tinished blank in its operative position for removal, such position being indicated at A, Figs. l and 4. To enable the ready remo "al of the blank b v the transfer mechanism, 'it isll'irst necessary to raise the blank out of the mold an inch or so, so that the blank transfer can grip it properly. Referring to l? l andyt, this apparatuscomprises amovable blank mold bottomtl, Fig. fl, pro` 'vided with a'stom Gi having an enlarged end G5 protruding rom the casing 66. This bottom is maintained in lower position by the spring G7 which presses the enlarged end of the stem and holds it down.

After the bank mold has arrived at position A, a kiek up7 or ejector lever 68 nasa/tsv p'ivoted to the shaft 69, Figs. 1 and 4, is caused to engage the stem and thereby push the bottom 63 upward carrying the blank with it until the tlange 7l on the blank is an inch or so above the topto the blank mold, where it may bey grippedby the transfer mechanism. The ejector lever 68 is operated by the cam 72, Figs. l and 4, secured at the proper position on the main operating shaft 27, and in the position shown in Ll,-the cam is holding the lever 68 away from the pin 65. Vvlhen the cam is rotated clockwise sullieient distance the pawl 'T3 formed on the lever GS will fall abruptly down onto the lov.v part of the cam, that is after the point 7l of the cani has passed the pawl 73. The counter weight- 68 assists the dropping action of the paivl. When the pawl 73 drops theother end ot the lever 68 will suddenly engage the pin 65 thus elevating the blank. at the proper time. At the proper interval the pawl 73 Will be raised and the lever 68 lowered to clear for the next operation.

.At the time the blank is raised the blank transfer mechanism is in the positions illustrated in Figs. l. and 7, and referring to such figures the blank transfer mechanism comprises vertical shaft '75 mounted for vertical and rotary movement in the bearing 7G and the leg 7T of the spider frame Which is supported by the vertical standard 78 at the Center ot the bottle mold table 3, and the vertical standards 79 and 80, Fig. l.

The vertical transfer shaft is slidably keyed or feathered for longitudinal movement in the sleeve 8l journaled in the bear ingl 76, and is rotated by the sleeve.

The sleeve 8l is rotated by means of the lever S2, Figs. l and secured to the lower end of the sleeve, and the lever is actuated by the link S3 connecting the lever 84 piv oted at S5 with the lever 82. The lever 8a is actuated by the bent link 8G secured to the other end ot' the lever S-l and to the bellerank lever 87 pivoted to the shaft 57', Fig. lhc horizontal arm o t' the bell-crank 87 carries a roller 88 which is held in engagement with the cani 89 secured to the operating shaft 27, by means of the counter Weight UO adj ustably mounted on an extension 91, Fig. 7, of the bell crank lever. The cam 89 rotates in a loekwise direction and through the medium ot' the mechanism just described causes the shattji' to oseillate about its aXis according to the motions imparted to the. bell era k lever ST'by the cam The shaft T5 is caused to reciprocate vertically by means ot' the lever 92- pivotedzat one end to the shaft 69, Figs. l and -7,- and which is provided vvith a forked end 93 which straddleg, the shaft T5 and lengages the adjustable nut lil. "lhe nut .itis locked in plat-e by the jam nut 95." The lever 9i?. is oseillated by the link eounerti'ng the lever resaca? v v 92 with the rocking lever 97 which is pivoted to shaft 57', the lever 97 being provided with a roller 98 which engages the earn 99 Secured to the main operating shaft 27.

il/hen the earn 99 is rotated clockwise the vertical shaft 75 is reciprocated vertically according to the motion imparted by the engagement to the cam 99 with the roller 9S on the levei97. The Weight of the shaft and all parts carried by it, is counterbalanced by the counter Weight 100 secured to a cable 101 which runs over the pulley 102 and is secured to the top end of the shaft T5.

The blank transfer mechanism for transferring a blank from a blank mold to a bottle mold situated on the bottle mold table 3, comprises a horizontal bracket 103, Figs. 1A

and 7, mounted on the shaft 75, s0 that its minimum heifrht is above the top ot the blank and bottle molds. ln the position shown in Figs. T and 1,v the complete transfer inotion, and in a position about tornove toward the blank to grip it. rlie blank gripping mechanism consists of pair of clamps 104- and 105 having circular jaws adapted to grip a blank. the jaws being pivoted to the bracket 103 by means of a bolt 106. To the clamp 10-1 is secured J(he. bevel gearsegnient 107 and to the clamp 105 issecured the bevel gear segment 108. are operated by means of a bevel gear 109 which meshes With the segments 107 and 10S thereby causing the clamps to rotate about the pivot 106 in opposite directions when the bevel gear 109 is rotated, and to open and close when the bevel gear is oscillated about its axis..

The bevel gear 109 is oscillated by the shatt 110 to which it is secured, and the shaft 110 is mounted upon the bracket 103 bv means of the two journals 111 and 112. The shaftis rotated in thedirection necessaryy to'cause the jaws 101 and 105 to open by means of the solenoid 113 carried by the shaft 75, the core 114 causing the lever 115, secured to the shaft 110, to be pulled down by the connecting link 11 when the solenoid is energized. The adjustable stop 11T secured to the shaft 110 limits the extent of opening of the jaws of the clamp by engaging the bracket 103ivhen the predeterinined limit is reached.

The clamp members are closed when the solenoid is denergized, by means of the tension spring 118 secured to the'. other end of vthe lever 115 and to the bracket 119 carf ried bythe shaft 75.

' T he current passing through the solenoid 113 controlled by means of the two cams 120 and 121, Figs. 14 and 1, mounted 0n the main operating shaft- 27 which cams operate the flexible switch 122 secured to a block 123 mounted upon the machine base 1. l/Vhen the cams 120 and 121 engage the switch 122,

The clamp jaws.

the contacts 124-. and 125 are connected by `means of the depression ot' `the switch 122, thus completing the circuit from the main Wires 126 and 127 through the branch Wires 128 and The cani 120 closes the circuit to open the clamps 101 and 10.5 in order to grip a blank and the cani 121 closesthc circuit to open the clani-p to release the blank when it has been transterred to the bottle mold.

rlhe four canis,`viz., cani controlling the vertical lift ot the shaft T53, cani S9 controlling the rotation ot the shaft 75, earn 120 controlling the opening of thc. transfer clamp preparatory to gripping a blank, and cain 121 controlling the opening of the transter clamp to release the blank, are so shaped and located on the mainoperating shaft 2T that :they ivi-ll 'actuate the transfer mechanisni in the following manner starting with the position shown in Figs. 1 and 2. Firstthe shatt drops until the clamp jaws 104- and 105 just clear the top of the blank mold, the clamp jaws are opened by cam 120, the

shaft is then rotated anticlock` dse, (looking down on the top of the machine), by earn 89 until the clamp jaws register with the raised blank, the close about the blank beneath the collar or" the blank,v earn raises the shaft until the Vbottom of the. blank clears the top of the blankinold, cam 89 rotates the .shalt 'l5 clockwise swinging the clamp around in a circular path until it registers directly above the opening in the bottle mold o at position B, cam 99 lowers shaft '75 until the clamp jaws just clear the top or' the bottle mold, cani 121 causes the transfer claino to open, dropping the blank into the bottle mold, cam 89 rotates shaft clockwise a shortA .distance `tor the 'jaws to Aclear the collar of the blank, cam 121 permits the spring 118 to close the clainp jaws, cain 99 then raises the shalt labout halt its vertical and the cani S9 linally rotates 'to remain open only sul'iicient time to clear the blank to grip it and release it in order to econoinize on. the electric current consumption. y

After a blank has been deposited in. a` blank mold at position ll, Fig, 1, the mold -table rotated clockwise by mechanism previously described, carrying the blank to position C. Here the blank remains While it is allowed to cool suliciently before being conducted to the blowing up station D by the next movement of the table. For this purpose live molds are used on the bottle mold table when tour are used on the blank mold table,

lvl/hen the bottle mold containing the blank arrives at the position 1`1,Figs, 1

and 8, the blank is registered withthe blow head 130, Figs. S and 14, which is of any approved type, operated by a piston 131 operating in the fluid cylinder 132, and adapted to descend upon the blank to blow into the form of a bottle. The blow head 1s supplied with compressed air through the flexible ho"A connection 133, Fig. 14, which receives air from the main supply pipe 134, and by means of a valve 1nechanism of common type carried by the blowhead air is permitted to blow into the hollow b lank when the head engages the top of the bottle mold Fluid pressure is supplied to the top and bottoni faces of the piston in the cylinder 132 by means of the tubes 135 and 13G, Fig. 14," and such fluid pressure is controlled by the valve 1371 Figs. 1 and 14, t0 which the tubes 135 and 1315 are indirectly connected. lefore the blow head 130 is permitted to descend to blow up the blank, the mold must be securely locked and for this purpose a locking cylinder 13S, Figs. 1, S and 14, is provided. which operates a forked lock 139 adapted to engage lugs 140 and 141, Fig. S, integral with each mold Section (the lugs being tapered and .one of the prongs of the lock being correspondingly tapered), to provide a wedging action in order to press the lugs together securely. The lock 139 is carried by the piston 142 which is reciprocated vertically within the cylinder 133, such motion being caused by compressed fluid operating on the top and bottom faces 'of the piston and supplied to such piston faces within the cylinders by means of the tubes 143 and 144 directly connected tothe three way plug valve 137 which controls the liuid supply to the cylinder 133.

rThe moid locking cylinder 13S and the l" blow up cylinder 132 are mounted upon the leg 145, Figs. 1 and H, of the spider frame which is supported by the standards 7o, 79, and S0, and are both supplied with Huid pressure from the main supply pipe 134, controlled b v the valve '137. The pipes 143 and 144, Fig. 14, leading from the valve 137 to the lock cylinder 13S, are of greater capacity and of shorter length than the tubes 135 and 136 leading to the blow up cylinder from the valve 137, and for this reason, the lock 139 will be actuated in advance of the blow'head, which is the effect desired.

The valve 137 is actuatedby the lever 146, Figs. 1, 4 and 14, carrying a counter weight 147 on one end and at the other connected to the operating lever 148 pivoted tothe shalt" 57 by means'of the connection rod 149.l The lever 148 carries a roller 150which engages the cam 151 secured to the main operating shaft 27 and is held in engagement therewith by the action of the counter weight 147 y In the position of the valve lever 140 shown in 4, the blow head and vmold. lock are maintained in raised position, shown in Fig, S, by air flowing through the tubes 144 :11u15-146 Fig. 14 to the bottom faces of tht` pistons, the air on the upper faces of the pistons having been exhausted through the tubes 135 and 143 and through the exhaust pipe 152.

The cam 151 is so adj usted upon the man1 operating shaft 27 that the mold lock and the blow head are caused to descend inline l1- ately after the table has moved a bottle nzold into proper position.

Should too much glass be supplied to the blank mold, what is called an over press',7 is the result which `is a blank having too much glass at the top and which will project slightly above the bottle mold when the blank is inserted therein. lf the blow head is permitted to descend upon an over press." it will shatter the glass and the pieces wil. fall into the mold and, aside from preventing proper workin;r of the'niold, time is lost in cleaning the mold so that it may be properly closed. To prevent the blow head from descending upon an over press, a selector mechanism is provided which comprises a selector rod 153, Figs. 1, S and 9, havnrg a flat widened lower end 154 Fig. 8 pivotedafl its upper end to a bracket secured to the top of the blow up c vlinder. 132.` The flattened end of the selector rod lies in the path of the blankso that it just clears the top 'of the mold but is engaged by an fover press. Pivoted to the selector rod 153, is. the notched latch bar 1.36 Figs. 8 and 9 provider'. nea'r its free end with a notch 157. vThe free end of the latch bar 156 is supported upon a, i

bracket 158 and when an over press engages the lower end 154 of the selector rod 153, moving in the direction toward the left1 F ig. 9, the latch bar will be moved to the left and the free end will drop and be latched into position beneath the annular flange 159 on the upper end of the piston rod extending :ibove the blow up7 eylinde 132, which carries the blow head;

Vhen the blow head 130 is caused to descend by the operation of the valve 137, the annular flange 159 will engage the top of the end of the latch bar 15G and further deseen of the blow head will be prevented, such sligl'it movement of the blow head not being sutlicient to 'cause it to engage the over the latch bar so vthat the selector rod ma) gravitate to its normal position showngin Fig.. 9, a horizontal lifting r'od160 is provided. This rod is supported atl .die end upon the ,blow up cylinder 132, so that it may slide between the bracketl 155 and the bracket 15S, Fig. 9 and carries :at the end adjacent the latch'bar 156 a flat leaf spring 161, Figs. 8 and 9.

. ldeizrrinfej` to Figs. 1, 12, 13 and 1-1 ine mechanism for removing a finished bottle from the mold and placino it upon an endless conveyor belt., comprises a vertical operating; shaft 214, Figs. l and journaled for yvertical and rotary movement in the bearenv-rags car 'ied by the spider leg 215 an d in the bearing; 216 mounted upon the hase 1. Thi. lower end of the shaft 21st is longitudinally slidally keyed or feathered in the sleeve 217 mounted 'for rotation in the bearing- 216, and is rotated by the sleeve 217. The bottle ineens? 21T, and which is connected to the link 219' which connects the lever 21S with another lever 220 pivoted at The other end of the lever 220 is pivoted tothe reciprocating linl' which is pivotcd to the bell-crank lever which is in turn pivot-ed on the shaft 181. The arm of the bell-crank lever carries a roller 225 which engages the cam 226 secured to the shaft 27. The roller is maintained in engagement with the cam 226 by means of the counter weight 223 adjustablysecured to the bell-crank lever extension 223. The cam is rotated in a clockwise direction and causes the vertical shaf 211, through the described media te oscillate about its axis according to the motion imparted to the bell-crank lever'223 by the Cain 226,

The vertical shaft 214 is caused to recip! 'rocate longitudinally by means of the oscillatine` lever 227 pivoted tothe shaft 22S. The free end of the leve 227 is forked at 229 and stiraddles the shaft 211 and engages an adjustable nut 250. The lever 227 is oscillated by the connecting' link AS1 which connects the lever 2i?? with the rocking lever 232. The free end of the rocking lever 232 carries a roller 253 which engages a cam 234 securetfl to the main operatingshaft 27. v The 'weight of the shaft 214 and all parts carried by it is counter balanced by the weight 235, Fig". 12, secured to the cable 236 which runs over a pulley and is connected to the upper end of the shaft 214. The shaft 21e is reciprocated longitudinally according` to the motion imparted to the rocking,- lever 232 by means of the cam 234, which rotates in a clockwise direct-lor The bottle gripping and transfer mechanism mounted upon the vertical operating shaft 21% and in the position shown in Figs. 1 and 12, the mechanism is about to be droi ped preparatory to swinging in toward the bottle to grip it after the mold opens.

"lhe mechanism comprises a, bracket 238, Figs. 1 and secured to the shaft 214-, and whiclL carries a pair of rcircular clamp jaws 239, and 210, adapted to grip a bottle beneath the collar` Each clamp jaw 239 and 210, Figs. 1, 12 and 13, is pivoted to the bracket 238, by the bolt- 2-11, and carries a bevel 2rear segment 242 and 243 respectively, Fi 13, a. bevel gear wheel 244, Figs. 12 and 13, meshes -Vith the segments 212 and 243,

.and when rotated about its axis, causes. the

gear segments with their attached clamp -to rotate in the opposite direction, and when the bevel gear Wheel 244 1s oscillated 1t lock in engagement with a bottle mold. Should the switch 278 be closed without first opening the valve 281, and the motor should start the machine before the plunger and the mold lock were raised, the machine would be cor iderably damaged. To prevent such an owurrence, the pneumatically controlled switch 279, Fig. 14, is employed which consists of a contact 27Sa carried upon a piston stem 282 which is secured to a piston 283 in the cylinder 284 which is supplied with 'anfroin the pipe 134 at a point'beyond the valve 181. The switch 278 is normally held open by the spring 285 engaging the piston Sand the end of the cylinder and closed by air ,'from the pipe 134. Therefore the air must be first turned on to close the switch 279 before it will be possible to start the electric motor 2l.

The complete operation of the machine is as follows z-The machine is rst started by opening the air supply valve 181 and then by closing the knife switch 278 and after-' ward cutting the resistanceout of the controller 280. After the machine is brought to full operation, a gathering of' glass on a punty or other mechanism is deposited in the blank mold and the punty shoved against the yielding switch arm 20 causing the shear to close and sever the glass: The table is thenl rotated clockwise a quarter turn after which the blank mold with the gathering therein is pressed into the form of the blank. After the plunger clears the mold the blank mold table is again rotated a quarter turn bringing the blank mold containing the blank into position for removal.

The blank is then raised out about an inch by the kick-up mechanism after which operation the blank transfer grips the blank, lifts it out of the blank mold, swings it over to a bottle mold and lowers thefblank therein, releasing the blank after 'depositing it.

' After the bottle mold has received the blank it is moved by two separate successive movements to the position where the blank is to be blown into the form of a bottle.

The mold lock now descends and locks the mold and imn'xediately afterward the blow head descends and blows the blank into the form of a bottle. After this operation'the mold containing the bottle is moved by two movements of the table to the posuccessi? sition w "ere the bottle is to be removed.

At this point the bottle centering lever descends and holds the bottle while the mold is being opened and as soon as the mold has been opened the centering lever releases its hold on the bottle and the bottfe is gripped by the bottle transfer. The bottle transfer grips the bottle, swings it clear of the mold and deposits it upon the conveyer where it is conveyed to the leer or lifted therefrom by lei'boya It will be observed that all the operative elements of the' machine are driven byv or controlled by a single operating shaft 27 which is continuously driven by the motor 2l, and therefore as each operative elemem f is independent of all other elements of the machine andoperated and controlled by a` for operating the clamp controlled by the y y 'shaft actuating means.
